Abstract
In order to explore the feasibility of applying DC four-electrode method based on embedded gauze or loop electrode in electrical resistance measurement of conductive composites, DC four-electrode method and DC two-electrode method for electrical resistance measurement of composites with different matrices and conductive fillers were compared, and the calculation method of contact resistance between electrode and conductive composites was proposed and verified. Research results show that DC four-electrode method can eliminate contact resistance between electrode and conductive composites, which exists in DC two-electrode method. The contact resistance is non-ohmic and can be calculated, and its value depends on the property of measured conductive composites. DC four-electrode method based on embedded gauze or loop electrode is suitable for electrical resistance measurement of conductive composites.
